UNTTED STATES FFTCEQ' ALANSON C. ESTABROOK, OF NORTl-IAMPTON,MASSACHUSETTS, ASSIGNOR TO THE FLORENCE MANUFACTURING COMPANY, OF SAMEPLACE.

SPECIFICATION forming part of Letters Patent No. 576,978, dated February9, 1897.

Application filed August I6, 1894.

To all whom it may concern,.-

Be it known that I, ALANsoN C. ESTABROOK,

a citizen of the United States, residing at Northampton, in the countyof Hampshire and State of Massachusetts, have invented certain -new anduseful Improvements in Brushes, of

Awhich the following is a specification, reference being had therein tothe accompan ying drawings.

The nature of the invention is set forth in full, clear, concise, andexact terms in the following description, in which reference is made tothe accompanying drawings, and said invention is particularly defined inthe claims x 5 at the close of this application.

My invention relates to brushes of that class in which the body of thebrush consists in a metallic shell, the latter usually being constructedin two parts or shells, namely, an zo upper portion or half, which isktermed the back, and a lower portion or half, which is termed the face,the latter being perforated for the reception of the bristles.

The present invention has for its object to provide a strong and durablebrush of the class mentioned of simple and inexpensive construction.

In the drawings, Figure l is a partial crosssection of a hair-brushembodying my inven- 3o tion. Figs. 2 and 3 are partial cross-sectionsshowing modifiedforms of reinforces for the upper shell or back. Fig. 4is a similar view of another form of reinforce and showing a metallicstrip for the joint between the shells of the back and face. Fig. 5 is aview corresponding in character with Fig. l, showing a furthermodification.

At l in the drawings is shown the upper portion or back of a two-partmetallic shell, 4o and at 2 the lower portion or face thereof.

The shell for the face is perforated for the reception of the tufts ofbristles 3. The inner ends of the tufts of bristles project inside saidshell and are shown as enlarged by burning 4 5 in the well-known manner.For the purpose of holding them securely in place, as also of stiffeningand reinforcing the shell for the face, the said shell is filled orpartially filled With a mass of composition et, which is placed 5o inthe shell in a plastic condition and is then allowed to set and harden.

Various well` sain No. 520,472. un modem known compositions may beemployed for this purpose. The composition flows around the inner endsof the tufts of bristles, which become embedded therein, and aretherebyheld firmly in place. The shell for the back, after being moldedor formed to the shape required by dies or the like, is provided with areinforce of wood 5, formed to the required shape and applied theretoand molded therein 6o under pressure, the shell being placed in a dieand the wood being molded therein to conform to the shell. In themolding operation the wood is also densified and forms a firm, butcomparatively light,l reinforce for the metal shell. 'Before the woodreinforce is placed in the shell the contact faces of the shell and woodare preferably covered with an adhesive, as shellac or the like, so thatafter the molding operation thevmetal shell 7o and wood reinforce arefirmly secured together. The wood reinforce 5 does not fill the shell lof the back, but the edges of the shell project beyond the wood, and inthe same manner the edges of the shell 2 of the face 75 project beyondthe composition. An intermediate reinforce 6, also preferably of woodand of sufficient thickness to fill the space between the reinforce 5and the composition 4, is provided. This intermediate reinforce is 8oprovided with a groove '7,preferably V-shaped, to receive the inturnededges of the shells l and 2. The upper and lower faces of theintermediate reinforce 6 are also preferably covered with an adhesive orsimilar securing means. The reinforce 6 is then placed between the backand face portions of the brush, and the edges of the shells l and 2 areturned inwardly and laid smoothly in the circumferential groove 7 formedto receive them 9o in the intermediate reinforce G. In this way theparts of the brush are rmly secured together through the medium of theintermediate reinforce G.

The operation is simple and may be readily 9 5 performed by the aid ofless skilful labor than is usually employed in the manufacture ofsuch'brushes, thus effecting a saving in the cost of construction. Aswill be obvious, the contour of the reinforces 5 and 6 may be made Iooto conform to any contour of shell, and the contours of the shells willdiffer with the character of the brush which is to be constructed. Inthe case of brushes having a handle these reinforces eXtend into thehandle.

In the modified form shown in Fig. 2 the construction is the same, butthe reinforces 5 and 6 of Fig. l are in this modified form formedintegral with each other, the reinforce thus produced being designated5l and its groove being designated 71.

In the modification shown in Fig. 3 the reinforces 52 and 62 are securedtogether by mechanical means, as, 4for example, brads or dowels, whichare shown at 8, and the circumferential groove 7 2 is formed at thejoint of the said reinforces, one side of said groove being on one sideof the reinforce and the opposite side on the other reinforce.

In Fig. 4 the reinforces are formed integral, as in Fig. 2, beingdesignated 53 in said Fig. 4, and the circumferential groove A73 isprovided with a backing-strip 9, into which the int-urned edges of theshell are bent, the said strip forming a backing for the joint betweenthe shells, stiffening the joint and insuring a better nish.

In the modification shown in Fig. 5 the backing-strip (here designated91) is formed with a central projection or bead 10 and a groove oneither side thereof, one of which grooves receives the inturned edge ofthe upper shell or back and the other the inturned edge of the lowershell or face 2, the bead projecting between the edges of the shells andserving not only to strengthen the joint and render the brush moredurable at this point, but also to improve the style and finish thereof.This modified form of backing-strip for the joint may be employed withthe wood reinforce in two parts 54, 64, or with a wood `reinforce formedintegral, as in Figs. 2 and i.

What I claim is- 1. A brush comprising two metallic shells, one for theface and one for the back, the shell for the face being perforated andhaving bristles in the perforations, a. mass of com position in saidshell securing the bristles in place and reinforcing the said shell, areinforce for the shell for the back, a portion of said reinforceentering the shell for the face, said reinforce being groovedcircumferentially and receiving the inturned edge of the shell for theface, substantially as set forth. v

2. A brush comprising two metallic shells, one for the face and one forthe back, the shell for the face being perforated and hav ing bristlesin the perforations, a mass of composition in said shell securing thebristles in place and reinforcing the said shell, and a reinforce forthe shell for the back, said re-V inforce consisting of two parts, oneof which is grooved circumferentially and receives the inturned edge ofeach of the said shells, substantially as set forth.

3. A brush comprising two metallic portions, one for theI face and onefor the back, the shell for the face being perforated and havingbristles in the perforations, a mass of composition in said shellsecuring the bristles in place and reinforcing the shell, a reinforcefor the shell for the back, a portion of said reinforce enteringthe'shell for the face and being grooved or reduced circumferentially,and a concave strip placed in the groove and receiving the inturned edgeof each of said shells, substantially as set forth.

In testimony whereof I aihx my signature in presence of two witnesses.
